Days of Wine and Roses (1962)

Joe Clay is a top-notch public-relations man. Anything a client wants, Joe can arrange, from dancing girls to an article in a prominent magazine. But part of the job is drinking, and Joe's ability to consume alcohol seems boundless. When he meets the very pretty Kirsten Arnesen, she prefers chocolate to alcohol; Joe's solution is Brandy Alexander, which is made up of brandy and crème de cacao. Joe and Kirsten eventually marry, but their love can't prevent the downward spiral brought on by alcohol. They try desperately to break the habit but continually relapse until only one of them manages to break free.
